Class ParameterSetTagger.KeyEntryComparator<K extends Comparable<K>,V>

java.lang.Object

de.jstacs.parameters.ParameterSetTagger.KeyEntryComparator<K,V>

Type Parameters:

K - the type of the key

V - the type of the value

All Implemented Interfaces:

Comparator<Map.Entry<K,V>>

Enclosing class:

ParameterSetTagger

public static class ParameterSetTagger.KeyEntryComparator<K extends Comparable<K>,V>
extends Object
implements Comparator<Map.Entry<K,V>>

This class implements a comparator on Map.Entry that sorts by the key of the Map.Entry. This class allows, for instance, to sort the Parameter in a ParameterSetTagger by their tags.
